To all whom z't-may concern:

Be it known that we, THOMAS ALLsoP and WALTER 'W. SIBsoN, citizens of the United A States, residing in Philadelphia, in the county of Philadelphia and State ofPe-nnsylvan-i'a, have invented certain new and useful Improvements in Dyeing-Machines, whereof the following is a specification, reference being had .to the accompanying drawings.

The invention relates-to dyeing machines and more particularly to that type known as circulatory machines.

In such machines, thegoods to be. dyed are carried within a perforated receptacle or cage revolving while partly submerged in the treating liquor. The goods thus under treatment, are directly exposed for .a considerable period during each rotation of the cage, to the atmosphere, and such exposure results in many instances in. oxidization, thereby causing streaks, stains, or similar objectionable blemishes.

To obviate these tendencies, the present invention is directed to means whereby the goods are constantly subjected to the action of the treatin liquors, notwithstandin the periodical wi-tfidrawal from immersion a ove referred to.

In the drawings, Figure I, is a plan view of a dyeing machine conveniently embodying our invention.

Fig. II, is a side elevation of'the same.

Fig. III, is an end elevation as viewed from the right of Fig. II, and

Fig. IV, is a cross sectional elevation of the same. i

As herein shown, our invention is applied to a dyeing machine which is associated with a circulatory system for the dye liquor and while such a device is ordinarily termed a dyeing machine, it is adaptable to a great many other uses such as washing, bleaching, etc. 7

In the drawings, 1, represents a vat or tub of any approved construction and having the substantially semi-circular cross section shown in Fig. IV. This vat is surmounted by a cover 2, so as to form a complete inclosure for a revolvingcage 3, which is partially submerged in the liquor contained in the said vat. Access may be had to said cage through a hinged door 4:, in the cover.- Said cage is perforated throughout for free circulation'of the liquor, and is fixed upon a central tubular shaft 5, extending longitudinally. ofthe' vat and journaled in suitable bearings in the side frames. Rotation is effected by means of a worm gear 6,driven by a worm 7, on power shaft 8, which is provided with the usual tight and loose pulleys 9, and 10, respectively. Tubular shaftb, is perforated within the confines of the vat and serves as a part ofthe circulatory system It is plugged, at the protruding right hand end, and at the left is in water-tight communication With a stationary pipe 11, which is in turn connectedto a vertical branch 12, leading to a centrifugal pump .13. The circuit is completed through a pipe 15, which extends into thelower part of the vat and is also perforated within the confines.

of the same.

When the pump is set in motion, the treating liquor is'circulated in the direction of the arrows in Fig. IV. In this way the goods in the cage are subjected to a constant current of the liquor in a direction radially outward from the central tubular shaft. The circulatory system is provided with a number of adjunctive connection-s, such as pipes to and from a supply vat, etc., but these form no part of the present invention. The present invention is directed to the following elements and their cooperation with a machine, such as above described.

Extending longitudinally through the vat cover, and symmetrically arranged above the rotating cage, is a'plur'ality of jet pipes 20, which are suitably perforated so that the spray resultant from the combination completely'envelops the portion of the cage extending above the level 30, of the dye liquor in the vat. Pipes 20, are extended beyond main circulatory system by means of a hand valve 22. I

When the machine is employed for washing, the auxiliary spraying system may be I directly supplied from a water pipe 23, un-

der control of a hand valve 25. When thus employed the valve 22, is, of course, closed.

In the dyeing of certain materials and also in the employment of certain dye stuffs, such materials are subject to the deteriorating efiects resulting directly from oxidization by exposure to the air, attending the lifting of the materials bodily out of the dye liquor as the cage completes that portion of its revolution above the same. Such oxidi-. zation usually results in. streaks, stains or uneven dyeing. It will thus be seen that by the present invention this danger is entirely obliterated, since the goods raised above the liquor in the manner just set forth is directly subjected to the enveloping spray afforded by the pipes 20. In washing, bleachin ,-etc., the11 same reasoning will apply equa ly as we Having thus described our invention, we claim:

1. A dyeing machine comprising a vat; means for passing the goods into and out of the dye liquor in the vat; in combination with means for completely envelopingthe goods in a spray of liquid when withdrawn from the dye liquor to protect the same from injurious efli'ects of atmospheric exposure.

2. A dyeing machine comprising a vat;

a perforated cage; means for revolving said 7 cage while partly submerged in said vat, in combination with an auxiliary spraying system directed to completely envelop-the excage, substantlally as described, and for the purpose set forth.

4. A dyeing machine comprising a vat; a perforated cage; means for revolving said cage while partly submerged in the said vat; a system for circulating the treating liquor through the said vat, in combination with an auxiliary spraying system directed to completely envelop the exposed portion of sald cage; and means for connecting said spraying system to the said circulating system, substantially as described and for-the purpose set forth.

In testimony whereof, we have hereunto signed our names at Philadelphia, Pennsylvania, this eighteenth day of October, 1917.
